Testing for Rough Volatility When Prices Are Purely Discontinuous

Journal of Time Series Analysis, EarlyView.
ABSTRACT We consider the problem of nonparametric testing for rough volatility, using high‐frequency data with a fixed time span, in a setting where the price is purely discontinuous. More specifically, we analyze the asymptotic properties of a test we developed in previous work in a pure‐jump setting.

Navigating Supply Shocks: Sector Resilience and Production Prices Through Stochastic Input–Output Modeling

Mathematical Finance, EarlyView.
ABSTRACT This study develops a novel multivariate stochastic framework for assessing systemic risks, such as climate and nature‐related shocks, within production or financial networks. By embedding a linear stochastic fluid network, interpretable as a generalized vector Ornstein–Uhlenbeck process, into the production network of interdependent ...

Inflation Inequality Across Household Income Groups in Brazil: Persistence, Trend and Volatility

The Manchester School, EarlyView.
ABSTRACT This article investigates inflation inequality across four income strata in Brazil (very low, low, middle, and high income) from July 2006 to April 2025, using the Headline IPCA as a benchmark. We test the hypothesis that inflation dynamics and transmission mechanisms are structurally unequal and disproportionately affect lower‐income ...
